RAT-TRAP.

Specification of Letters Patent.

Patented Sept. 3, 1918.

Application filed June 21, 1918. Serial No. 241,182.

To all whom it may concern.'

Be it known that I, JOHN VAL. KLEIN, a citizen of the United Sta-tes, residing at Renvi'lle, in the county of Renville and State of Minnesota, have invented a new and usev ful Rat-Trap, of which the following -is a specication.

This invention relates toi-at traps particularly designed for use lin grain elevators, etc., although it is also capable of use in any place where rodents are to be trapped. One

of the objects of the invention is to provide...

partment and which, when in active posi-- tions, serve to hold the door or doors of said compartment so that the rodents cannot be removed accidentally or otherwise.

Vith the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and po-inted out in the claims, it being understood that various changes may be made in the construction and arrangement. of the parts without departing from the spirit or sacrificing any of the advantages of the invention as set forth in the appended claim.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a plan view of the trap, parts being shown in Section.

Fig. 2 is an enlarged section on line 2-2,

Fig. 1.

4ig. 3 is a side elevation, a portion being shown in section.

Fig. 4 is an end elevation.

Referring to the figures by characters of reference, 1 designates a cage like receptacle the top of which is preferably solid while the sides are formed of bars, as shown, there being a door 2 at one or both sides which can be fastened in closed positions by any suitable means, indicated generally at 3. An extension 4 is provided at each end of the receptacle and has av bottom 5 inclined downwardly toward the receptacle, there being a ixedrpartition 6 between the upper portion of the receptacle and each extension and a. hinged door 7 suspended from each partition for normally closing communication between the extension andthe receptacle. These doors are adapted to swing inwardly into the receptacle-when moved to open positions and arms 8 having weights 9 and connected to the doors 7 serve to hold the doors normally closed. These arms extend through the walls of the receptacle, there being openings 10 provided therefor.

Hingedly, mounted within each extension 4 is a trap door 11 adapted to swing downwardly onto the inclined bottom 5 but nor# mally held elevated and in line with the top of the door 7 by an arm 12 connected to the trap'door and provided with a weight 13. A compartment is thus formed in each extension above the trap door, this compartment having an inlet 14 at one side. The top of the receptacle 1 is extended over the compartments and doors 15 are provided therein over the compartments to give access thereto when desired.

Secured along one side of each extension 4 below and outside the inlet 14 thereof is a flange 16 having a slot 17 therein. Pins 18 extend upwardly from the top of each'extension directly over the inlet 14 thereof.

Arranged at each side of the receptacle 1 is a runway or incline 19 in the form of an elongated box having a central, longitudinal, vertical partition 20 forming two passages within the incline. The lower end of each incline, which is open, is adapted torest on the floor and to be secured to the side of receptacle 1 in any suitable manner, as by means of hooks 21. The upper end of the incline has a lateral outlet 22 adapted to register with the inlet 14 and overhung by a flange 23. This flange is adapted to rest on the extension 4 and has openings 24 for the reception of the pins 18. Studs 25 extend downwardly from the bottom of the outlet portion of the incline and are adapted to extend into the slot 17, thus to hold the incline secured to the receptacle 1. The inolines, when in position, are adapted to extend across the doors 2, thus to prevent them from being opened aoeidentally or otherwise without removing the inelines.

IVhen bait placed in the receptacle, the rodents will crawl up the inelines 19 and pass through the outlets 22 in the inelines to the receptacles above the trap doors ll. As soon as the weight of one or more rodents is applied to a trap door, the door will swing ifiownwardly, causing the rodent to fall against the door 7 which will thus swing open and Jdien closed1 leaving the rodent looked in the receptacle 1. rl`he herein described trap can be made ol very large capacity and four rodents can be discharged thereinto at one time, thus rendering the trap particularly desirable for use in gra-in elevators and other places where they are found in large numbers.

The hooks 2l ean not only be provided at the lower ends of the inelines for fastening then to the receptacle l, hut they can also be arranged at the upper ends thereof.

IVhat is claimed is A trap including a receptacle having a side door, an extension at one end ot' the receptacle provided with an inlet, upstanding connecting pins upon the extension, a slotted flange on said extension, an incline at one side of the reeeptacle and extending across the door to prevent opening thereof, said ineline opening into the inlet of the extension, and separate means on the ,inc-line for engaging the pins and flange respectively.

In testimony that I elaini the foregoing as my oivn I have hereto aiiXe-d my signature in the presence of two Witnesses.
